[0002] Transport device
[0003] Description
[0004] The invention relates to a transport device comprising at least one frame which has a substantially central recess which extends substantially parallel to a longitudinal direction of the transport device, so that the frame, when viewed in the longitudinal direction, has a cross-section open on one side in the area of the recess.
[0005] Such transport devices, which can be designed as heavy-duty vehicles or heavy-duty modular vehicles, or as transport units such as transport bridges or trough bridges (e.g., excavator bridges), are widely known and used in the heavy-load sector for various applications. When transporting heavy loads, it is usually not only the weight but also the dimensions of the load that are crucial. Therefore, the aforementioned transport devices with a centrally located recess, which can also be described as an excavator trough, are frequently used for transporting particularly tall loads. This recess can be designed to accommodate at least part of the load, such as an excavator bucket, excavator arm, excavator stick, or similar component.This ensures that the transport equipment, including the load being transported, has the lowest possible overall height, so that even with comparatively high loads, tunnel or bridge passages are still possible.
[0006] However, a disadvantage here is that such transport devices are generally only well suited for loads that have a comparatively high dimension in the vertical direction, but are usually less suitable for transporting particularly heavy and / or wide loads, so that for such 222770PDE / MLRH 2
[0007] Transport tasks regularly require the use of different transport equipment. This inevitably means that a carrier, such as a transport company, must regularly maintain a large number of different transport devices in order to handle various transport tasks.
[0008] It is therefore an object of the invention to provide a transport device which can remedy this situation and is particularly versatile in its application.
[0009] According to the invention, this problem is solved by a transport device comprising at least one frame which has a substantially central recess which extends substantially parallel to a longitudinal direction of the transport device, such that the frame, when viewed in the longitudinal direction, has a cross-section open on one side in the area of the recess, wherein the frame is further associated with an adapter which can be detachably attached to the frame in the area of the recess and, in a state attached to the frame, extends at least section by section substantially parallel to a lateral direction of the transport device which is substantially orthogonal to the longitudinal direction, and wherein, in the state of the adapter attached to the frame, the frame, when viewed in the longitudinal direction, together with the adapter, forms a closed cross-section at least section by section in the area of the recess.
[0010] Due to the fact that the adapter can be detachably attached to the frame according to the invention, the transport device can be operated in at least two different configurations, namely in a first configuration in which the frame is free of the adapter, and in a second configuration in which the adapter is attached to the frame in the area of the recess.
[0011] In the first configuration, the frame thus has a cross-section open on one side in the area of the recess, so that parts of a with the222770PDE / MLRH 3
[0012] The transport device allows the load to be transported, such as an excavator bucket or similar, to be received or inserted into the recess. The first configuration is therefore particularly suitable for transporting especially tall loads and / or for situations where the transport device, including the load being transported, should have the lowest possible overall height.
[0013] The second configuration is preferable when the same transport device is used to transport comparatively wide and / or heavy loads, which are preferably to be supported substantially across the entire width of the transport device. In the second configuration, the adapter can thus form part of the transport device's loading platform. Furthermore, the second configuration allows for greater frame stiffness because the frame, together with the adapter, forms a closed, preferably substantially rectangular or circular, cross-section, at least in certain sections (i.e., in the area where the adapter is attached to the frame). This closed cross-section is also referred to as a closed tube in technical circles. The first configuration can therefore also be described as an open-tube configuration.
[0014] In the second configuration, the cross-section can, for example, be closed along a circumferential direction extending around the longitudinal direction and / or a longitudinal axis of the transport device, while in the first configuration the cross-section can be open at least on one side along the circumferential direction extending around the longitudinal direction and / or the longitudinal axis of the transport device.
[0015] In order to at least partially cover the recess, a preferred embodiment proposes that, in the state of the adapter being attached to the frame, as seen from a top view of the transport device, the adapter and the recess are arranged to overlap at least partially. 222770PDE / MLRH 4
[0016] Additionally or alternatively, in the state of the adapter being attached to the frame, the adapter can be arranged in the longitudinal direction in the area of at least one end face of the frame in order to be able to use the adapter not only for increasing the stiffness of the frame, but also, for example, for coupling the transport device with another transport device or the like.
[0017] In a further development of the two aforementioned embodiments, it is additionally proposed that the adapter be arranged in the region of the frame's end face such that, in plan view, it projects beyond the frame by a predetermined amount in the longitudinal direction. This ensures that the transport direction can be coupled to another transport device via a projecting section of the adapter, and / or that a tensile force or the like to be transmitted between the transport device and the other transport device can be at least partially transferred to the other transport device via the projecting section of the adapter, or vice versa.
[0018] To achieve particularly precise positioning and space-saving mounting of the adapter, the frame can have at least two recesses arranged opposite each other with respect to the recess, which are designed and intended to at least partially accommodate opposite end regions of the adapter. Furthermore, a longitudinal force acting on the adapter can be introduced into the frame via the mounting of the adapter in the recesses. Preferably, the recesses are arranged on at least one end face of the frame, preferably one pointing in the longitudinal direction. More preferably, the frame can have a pair of recesses arranged opposite each other with respect to the recess on opposite end faces, in order to allow the insertion of an adapter on each end face of the frame. 222770PDE / MLRH 5
[0019] To further increase the stiffness of the frame and / or to further improve the suitability of the adapter as part of a loading platform, according to a further embodiment the adapter can comprise at least two oppositely arranged crossbeams which extend substantially parallel to the width direction, and at least one longitudinal beam which connects the two crossbeams and extends substantially parallel to the length direction, wherein the adapter preferably has essentially the form of a double-T beam.
[0020] If a cross-section that is closed in the longitudinal direction, preferably completely, is formed in the area of the recess and / or the adapter is to be used additionally as a loading surface, a further development proposes that the at least two oppositely arranged crossbeams are connected to each other away from the longitudinal beam by means of cover elements, preferably cover plates, arranged oppositely to the longitudinal beam.
[0021] If the adapter itself is also intended to support parts of a comparatively heavy load, a support element can be additionally or alternatively assigned to the adapter, which is supported at one end by a base of the recess and at the other end by the adapter.
[0022] To enable the transport device to be easily connected and disconnected from another transport device using the adapter, the adapter can include at least one pair of through-holes designed and intended to connect the transport device to another transport device, which is preferably arranged longitudinally in front of or behind the transport device. The through-holes can preferably be designed to accommodate connecting elements, such as screws or bolts. The adapter can also be connected to various other transport devices via the through-holes, which only need to be compatible with the interface to the through-holes. 222770PDE / MLRH 6
[0023] In order to be able to connect the transport device with another transport device which differs from the transport device, for example with regard to a height and / or an interface and / or an interface height, it is proposed according to a further embodiment that the adapter comprises at least one further pair of through holes which is arranged, preferably in a height direction of the transport device, spaced apart from the at least one pair of through holes.
[0024] According to a particularly preferred embodiment, the transport device is designed as a heavy-duty modular vehicle comprising at least one axle assembly arranged on the frame and having at least one wheel mounted thereon, preferably two wheels mounted in opposite directions. Preferably, the heavy-duty modular vehicle is designed and intended to be coupled with another heavy-duty modular vehicle and / or a transport unit, in particular a bridge, for example a culvert bridge or an excavator bridge, and / or a towing unit, in particular a tractor unit. The longitudinal direction can then be the longitudinal direction of the heavy-duty modular vehicle. Furthermore, the lateral direction can preferably be the lateral direction of the heavy-duty modular vehicle. Depending on the desired application, the heavy-duty modular vehicle can also be coupled with any number of other heavy-duty modular vehicles.The heavy-duty modular vehicle and / or the further heavy-duty modular vehicle can comprise one or more axles, which may preferably be arranged one behind the other in the longitudinal direction of the vehicle. Furthermore, the heavy-duty modular vehicle can have at least two axle assemblies, which are arranged oppositely to each other on the frame with respect to the recess. The heavy-duty modular vehicle can also be, for example, a towed or a self-propelled heavy-duty modular vehicle.
[0025] To ensure that the transport device, designed as a heavy-duty modular vehicle, is as versatile as possible, the additional heavy-duty modular vehicle 222770PDE / MLRH 7
[0026] be identical to the heavy-duty modular vehicle or differ from the heavy-duty modular vehicle in terms of vehicle type and / or number of axle assemblies and / or length in the longitudinal direction of the vehicle.
[0027] Alternatively, the transport device can be designed as a transport unit, in particular a bridge, for example a trough bridge or an excavator bridge, or as a coupling unit of a bridge, which is designed and intended to be coupled with another transport unit and / or a heavy-duty modular vehicle and / or a towing vehicle. The transport unit can therefore be designed in such a way that it is only suitable for receiving the load on its own, but only acquires its ability to move when connected to another transport unit and / or a heavy-duty modular vehicle and / or a towing vehicle.
[0028] It should also be added that the transport device may further comprise a coupling unit, in particular a bolt-and-latch coupling, which may be designed and intended to be coupled to a corresponding coupling unit, in particular a corresponding bolt-and-latch coupling, to another transport device, in particular to another transport unit or to another heavy-duty modular vehicle, or to a towing vehicle.
[0029] According to a further preferred embodiment, the adapter can be designed and intended to receive a telescopic element, in particular a telescopic tube, displaceably along the longitudinal direction, wherein the telescopic element is preferably lockable in a plurality of predetermined extension positions in the longitudinal direction on the adapter.
[0030] Preferably, the adapter can additionally have an adapter-side coupling unit, in particular an adapter-side bolt-and-latch coupling, which is designed and intended to be coupled to the frame of the transport device with a coupling unit, in particular a bolt-and-latch coupling. Consequently, the adapter has a further 222770PDE / MLRH 8
[0031] The function consists of accommodating the telescopic element in order to provide transport devices that can be varied in length and can be operated in either the first or second configuration described above.

[0042] Figure 6: a transport device according to a further embodiment according to the invention, which comprises a telescopic element.
[0043] In Figures 1a and 1b, a transport device according to an embodiment of the present invention is generally characterized by reference numeral 100. The transport device 100 is designed as a heavy-duty modular vehicle. The heavy-duty modular vehicle 100 comprises a frame 102, which has a substantially centrally arranged recess 104 extending substantially parallel to a longitudinal direction L of the transport device 100, such that, when viewed in the longitudinal direction L, the frame 102 has a cross-section open on one side in the region of the recess 104, in the illustrated embodiment opening upwards. The open cross-section is best seen in Figure 1b.
[0044] As can be seen in Figure 1a, the frame 102 is further associated with an adapter 106, which can be detachably attached to the frame 102 in the area of the recess 104. Figure 1a shows that the adapter 106 extends substantially parallel to a lateral direction B of the transport device 100 across the recess 104, with the lateral direction B being substantially orthogonal to the longitudinal direction L. In the state shown in Figure 1a, the frame 102 consequently has a closed cross-section when viewed in the longitudinal direction L, which is formed by the substantially U-shaped frame 102 and the adapter 106 extending in the lateral direction B. In Figure 1a, the frame 102 together with the adapter 106 thus forms a substantially rectangular or tubular cross-section, which is also referred to in technical circles as a closed tube. In Figure 1b, however, the state with a cross-section open at one end, i.e.,Open tube (excavator trough), shown. 222770PDE / MLRH 10.
[0045] As can also be seen in Figure 1a, the adapter 106 and the recess 104 are arranged to overlap at least partially, and in the illustrated embodiment completely. In the area of the end face 108 of the frame 102, the adapter 106 also projects forward in the longitudinal direction L by a predetermined amount to serve as a contact surface when the heavy-duty modular vehicle 100 is coupled to another heavy-duty modular vehicle 400 or 500 via the adapter 106, as shown, for example, in Figures 3a and 4a.
[0046] In order to ensure that the adapter 106 is positioned correctly in the frame 102 and that adequate force is transmitted through the adapter 106 into the frame 102, the frame 102, as can best be seen in Figure 1b, also has two recesses 110a and 110b arranged opposite each other with respect to the recess 104, which are designed and intended to at least partially accommodate opposite end regions 106a and 106b of the adapter 106.
[0047] In the illustrated embodiment, the adapter 106 itself has at least two oppositely arranged crossbeams 112a and 112b, which extend substantially parallel to the lateral direction B. Furthermore, the adapter 106 comprises a longitudinal beam 114, which connects the two crossbeams 112a and 112b and extends substantially parallel to the longitudinal direction L. In the illustrated specific embodiment, the adapter 106 therefore essentially has the form of a double-T beam. However, it should be noted that the adapter 106 can also have a plurality of longitudinal beams 114, for example, arranged parallel to one another.
[0048] In order to provide a substantially enclosed loading area on the heavy-duty modular vehicle 100, the oppositely arranged crossbeams 112a and 112b are connected to each other by cover elements 116a and 116b, which are arranged oppositely to the longitudinal beam 114 and which may preferably be designed as cover plates. 222770PDE / MLRH 11
[0049] Cover elements 116a and 116b are arranged away from the longitudinal beam, that is, on both sides of the longitudinal beam 114.
[0050] If the adapter 106 is to bear particularly heavy loads, a support element not shown in Figure 1a can also be assigned to the adapter 106, which can be supported at one end on a bottom of the recess 104 and at the other end on the adapter 106, for example in the area of the crossbeam 114.
[0051] To connect the heavy-duty modular vehicle 100 with another heavy-duty modular vehicle 400 or 500 or a transport unit 200, such as a transport bridge or the like, via the adapter 106, the adapter 106 comprises on opposite sides two pairs of through holes 118a and 118b, which can interact with corresponding through holes of another adapter or another suitable interface, such as a standard interface of another heavy-duty modular vehicle or another transport unit, by means of suitable connecting means, such as screws or bolts.
[0052] As can be seen in Figure 1a, the pairs of through-holes 118a and 118b are arranged at different height levels, i.e., one above the other. This means that the heavy-duty module vehicle 100 can be coupled not only to another heavy-duty module vehicle 400, which has a different coupling height than the heavy-duty module vehicle 100, as shown in Figures 3a and 3b, but also to another heavy-duty module vehicle 500, which has the same coupling height as the heavy-duty module vehicle 100, as shown in Figures 4a and 4b. In Figures 3a and 3b, the heavy-duty module vehicle 100 has a coupling height of, for example, approximately 800 mm, which is somewhat higher than the coupling height of the other heavy-duty module vehicle 400, which may be, for example, only about 750 mm. In Figures 4a222770PDE / MLRH 12
[0053] In contrast, for 4b the coupling heights can be the same, meaning that both are approximately 800 mm, for example.
[0054] As can be further seen in Figure 1a, the adapter 106 can additionally be fastened to the frame 102 by means of fasteners, such as screws 120. Furthermore, the heavy-duty modular vehicle 100 comprises, in a manner known per se, two oppositely arranged axle assemblies 122a and 122b, each of which has two wheels 124 arranged thereon, which are rotatable about a pivot axis R. The heavy-duty modular vehicle 100 can also be a towed or a self-propelled heavy-duty modular vehicle.
[0055] Finally, the heavy-duty modular vehicle 100 can also include a coupling unit 127, which can, for example, be designed as a bolt-and-latch coupling and can be designed and intended to be coupled with a corresponding coupling unit, in particular a corresponding bolt-and-latch coupling, of another transport device, such as the additional heavy-duty modular vehicle 400 or 500. Coupling of adjacent transport devices, such as the heavy-duty modular vehicle 100 and the additional heavy-duty modular vehicle 400 or 500, can therefore be effected both by means of the adapter 106 via the through-holes 110a, 110b, and by means of the coupling unit 127.
[0056] Figures 2a to 2c show a further embodiment of a transport device 200 according to the invention, in which analogous components are identified by analogous reference numerals, but increased by the number 100 compared to Figures 1a and 1b. As can be seen in Figures 2a and 2c, the adapter 206 is formed only as a crossbeam, that is, it comprises only a section extending substantially parallel to the lateral direction B. In the illustrated embodiment, the transport device 200 is designed as a transport unit in the form of a bridge and further comprises a loading platform 205, which extends
[0057] also extends in the longitudinal direction L and may be designed and intended to bear a load (not shown).
[0058] As shown in Figure 5, which again depicts the heavy-load module vehicle 100, the heavy-load module vehicle 100, with adapter 106 removed, can be connected on the one hand to a transport device 200 in the form of a transport unit, such as a bridge, and on the other hand to another heavy-load module vehicle 600 in the form of an end chassis with a recess 604, the cross-section of which can essentially correspond to the recess 104. The axle assemblies of the end chassis 600 are not shown in Figure 5 for clarity. To ensure adequate force transmission in the longitudinal direction L even with adapter 106 removed, pressure pieces 126a and 126b can be inserted in the area of the recesses 110a and 110b, which can interact with corresponding pressure pieces 226a and 226b on the transport device 200.
[0059] Finally, Figure 6 shows another embodiment of a transport device 300, where analogous components are also designated with analogous reference numerals, but the number is increased by 200 compared to Figures 1a and 1b. The transport device 300 can also be a heavy-duty modular vehicle, essentially analogous to Figures 1a and 1b, although no axle assemblies are shown in Figure 6. As can be seen in Figure 6, the adapter 304, which is removable from the frame 302, is designed and intended to slidably receive a telescopic element 328, which can, for example, be designed as a telescopic tube, along the longitudinal direction L, according to the illustrated embodiment.The telescopic element 328 can preferably be locked in a plurality of predetermined extension positions in the longitudinal direction L on the adapter 304 in order to achieve correspondingly different lengths of the transport device 300 or 300.
[0060] to be able to adjust vehicle lengths. Figure 6 also shows that the adapter 304 can also be connected to the frame 302 via the bolt-latch coupling 327.
